Hi all, I cannot use material shaders on my iMac (late 2009 model) equipped with an ATI graphics card (ATI Radeon HD 4670 256 MB VRAM). I only get a few fps standing on ground at an isolated airfield. There is almost no objects. Every 10 times I get 60 fps in cockpit view with no changes except restarting flightgear. Toggling through different view gives different frame rates where the tower views always gives around 60 fps and the others give 2-5 fps (except the occasional 60 fps I get in the cockpit view).
In cases when I get 60 fps in cockpit view my computer maintains 60 fps with 3D clouds and skydome scattering turned on. The frame rate is stable even flying through the magnificently rendered clouds. If I turn of material shaders I always get 60 fps in all different views. (Is 60 fps a maximum reading, I never seem to get higher readings?) On my Macbook Pro (early 2008) model, I always get 60 fps staying away from the 3D clouds but the frame rate drops to 20 fps when I fly through clouds. The MBP has a GeForce 8600M GT 256 MB VRAM. The test on my iMac was done on yesterdays source from the various repositories and everything is compiled with -g -O3 (-O2 gives the same numbers). I have also tested a couple of Tat's git snapshots from the macflightgear site and they give similar negative shader effect. I read through many posts on flightgear and shaders on the web but nothing has resolved my issue. Is the above a flightgear issues or is it my hardware? I haven't noticed anything strange with my iMac and Apples extended hardware test does not report anything.
